Some of the “Top 40 Nature Photographs Of All Time” are being auctioned off to support environmental activities in support of the 40th anniversary of Earth Day.
Here is more information from the Flickr site:
The International League of Conservation Photographers, a fellowship of the top professional conservation photographers working today, was recruited to nominate nature photographs that the member photographers considered to be “the best,” in whatever way they chose to define it…
Some of these photographs have been generously donated by the photographers or their representatives for the inaugural Christie’s Green Auction in support of Conservation International, Oceana, Natural Resources Defense Council, and the Central Park Conservancy.
I’m adding the link to The Best Earth Day Sites.
